Benefits of technology

Ensures precise centering and adjustable tilting in all photographing aspects, allowing for omnidirectional swinging and tilting of the lens, enhancing photographic flexibility and accuracy.

Problems solved by technology

However, in the related art lens barrel, since the lens holding frame that holds the lens is supported only by inserting the guide pins through the long-hole shaped rectilinear grooves drilled along the optical axis direction in the outer periphery of the reference cylinder and the cam grooves formed along the circumferential direction of the cam cylinder, the lens holding frame may not be held in a state where the optical axis of the lens held by the lens holding frame is made to coincide with the optical axis of the optical system, so that centering may not be surely performed.

Embodiment Construction

[0033]Referring to the drawings, embodiments of a swinging and tilting mechanism, a lens barrel and an image capture apparatus to which the present invention is applied are now described in detail.

[0034]A camera 1 according to an embodiment of the present invention is shown in FIGS. 1A and 1B. The camera 1 is a digital still camera or a camera using silver-salt film, and includes a camera body 2 and a photographing lens 3 detachable from the camera body 2.

[0035]The camera body 2 is formed into a substantially rectangular shape having an outer form easy for a user to grip with one hand, and in a front surface 2a, a lens mount 5 to which a lens barrel of the photographing lens 3 described later is attached detachably is formed, and a grip portion 6 is formed so as to protrude. The camera body 2 is stably gripped by the user by having the grip portion 6 protruded on a front surface 2a side. Moreover, in the camera body 2, a shutter button 7 is formed on the grip portion 6 so that the u...

Abstract

A swinging and tilting mechanism includes a lens, a lens holding frame that holds the lens, a fixed member, and an operation member. The fixed member includes a rotation support portion that rotatably supports the lens holding frame in at least one side surface in one direction perpendicular to an optical axis of an optical system, and a tilting support portion that supports the lens holding frame tiltably in a direction of the optical axis in at least one side surface in another direction perpendicular to the optical axis and the one direction. The operation member rotates the lens holding frame supported by the fixed member with the rotation support portion used as a support point, and tilts the same along the tilting support portion.

Description

CROSS REFERENCES TO RELATED APPLICATIONS[0001]The present invention contains subject matter related to Japanese Patent Application JP 2008-032260 filed in the Japanese Patent Office on Feb. 13, 2008, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a swinging and tilting mechanism, a lens barrel, and an image capture apparatus making up an optical system enabling so-called swinging and tilting photographing based on the Scheimpflug principle.[0004]2. Description of the Related Art[0005]In related art, a lens barrel enabling swinging and tilting photographing by displacing an optical axis of a photographing optical system from a center of a film or an imager device has been provided. This type of lens barrel includes a bellows that connects a support plate attached to a lens mount and a support plate provided on a body mount side, using a bellows attachment, and a support...
